The climate requirement for Bitter Gourd Production:

Mainly a warm season plant, bitter gourd thrives in hot and humid climates.

Best Soil for Bitter Gourd Farming:

The best medium for the seeds is a fertile, well-drained soil with a pH ranging from 5.5 to 6.7, enriched with organic matter, such as compost or dried manure. But it will tolerate any soil that provides a good drainage system (sandy loam soil, but it will grow in areas with poorer soils.) It should be in a frost-free area and will prefer the climate with daytime temperatures between 24°C and 35°C. The soil must be prepared well by adding organic matter before planting. Seeds soaked in water will germinate sooner. Soil temperature for germination is at least 20°C to 25°C

Preparation of Land for Bitter Gourd Plantation:

Plow the field to a fine tilth and dig pits of 30cm x 30cm x 30cm size at 2 x 1.5m spacing and form basins.

Time of Sowing and Seed Rate of Bitter Gourd:

The seed is sown from January to March for summer season crop, June-July for rainy season crop in the plains and March to June in the hills. The seed rate is 4 to 5 kg/ha.

Sowing Method of Bitter Gourd:

The seed is sown by dibbling method at a spacing of 120×90 cm. Generally, three to four seeds are sown in a pit at 2.5 to 3.0 cm depth. The seeds are soaked in water overnight before sowing for better germination. Seed germination was enhanced by soaking the seeds for 24 hours in a solution of 25 to 50 ppm GA and 25 ppm boron. In flatbed, layout seeds are dibbled at the spacing 1-meter x 1 meter.

Pollinating of Bitter Gourd:

While vines are blooming over a six month period, Bitter Melon needs insects such as honeybees to carry out the pollinating process for setting fruits. If the insects are not available in your area, the pollinating process can be done manually, by picking up male flowers and transferring pollens (face-to-face touching the center part of flowers) to female flowers. Female flowers have a fat section between the flower and vine stem. This process should be carried out when flowering is active during the daytime. If the pollination is a success, the fat portion will grow into full-size fruit.

Irrigation requirement for Bitter Gourd Plantation:

Weed Control in Bitter Gourd Farming:

After cultivation Hoeing is done thrice to control weeds. Provide stakes to reach the pandal (2 m).  Spray Ethrel 100 ppm (1 ml dissolved in 10 lit of water) four times from 15th day after sowing at weekly intervals.

Diseases and Pests of Bitter Gourd Plants:

Like other cucurbits, Bitter Gourd vines are susceptible to several insect pests and diseases like:

  • Mites: Spray dicofol 18.5 % SC @ 2.5 ml per liter of water.
  • Aphid: Spray Imidachloprid @ 0.5 ml/lit along with sufficient quantity of stickers like Teepol, triton X100, apsa, etc., for better adhesion and coverage.
  • Beetles, fruit flies, and caterpillars: Beetles, fruit flies, and caterpillars can be controlled by spraying Malathion 50 EC 1 ml/lit or Dimethoate 30 EC 1 ml/lit or Methyl demeton 25 EC 1ml/lit.
  • Powdery mildew: Powdery mildew can be controlled by spraying Dinocap 1 ml/lit or Carbendazim 0.5 g/lit.
  • Downy mildew: Downy mildew can be controlled by spraying Mancozeb or Chlorothalonil 2 g/lit twice at 10 days interval.

Manure and Fertilizers requirement for Bitter Gourd Plants:

Apply 10 kg of FYM per pit (20 t/ha) 100 grams of NPK 6:12:12/pit as basal and 10 grams of N/pit 30 days after sowing. Apply Azospirillum and Phosphobacteria 2 kg/ha and Pseudomonas @ 2.5 kg/ha along with FYM 50 kg and neem cake @ 100 kg before the last plowing.

Harvesting and Yield of Bitter Gourd:

Harvesting is done when the fruits are still young and tender at every alternate day. Picking should be done carefully so that the vine may not be damaged. The fruits should not be allowed to mature on the vines. The harvested fruits may be stored for 3 to 4 days of in-cool condition. The yield is 60 to 100 quintal/ha.

Seed Production of Bitter Gourd:

Some vines should be left in the field to produce gourds for seed. Seeds continue to mature inside the gourd even after harvest. The seed that is sorted, washed and stored in a cool, dry spot, will remain viable for 2-3 years.

Leave some fruits to reach full maturity if they have to be reserved for subsequent crops. When fully mature, the fruits will break open on their own and release brown or white seeds which can be collected.

Marketing of Bitter Gourds:

Bitter Gourd can be transported to local vegetable markets or some herbal companies directly.
